`\NINDOW-OPERATING MECHANlSM.

SPECIFICATION forming part of Letters Patent No. 639,329, dated December 19, 1899. Application filed September 29, 1899. Serial No. 732,095. (No modela To all whom, it may concern.;

Be it known that I', JOHN PORTEREINE YAWN, a citizen of the United States, residing at Moselle, in the county of Jones and State of Mississippi, have invented anew and useful NVindow-Operating Mechanism, of which the following is a specification.

My invention relates to novel mechanism for raising and lowering windows7 and more particularly to mechanism by means of which all of the windows in a building may be simultaneously adjusted. l

The object of the invention is to produce a simple and inexpensive device which may be quickly mounted at any convenient point in a building and connected with the several windows in a room, or, if desired, with all the windows of the house, and which when so connected may be easily operated to effect the complete or partial opening or closing of the several windows simultaneously.

Referring to the drawings, Figure 1 is a general view'. illustrating the application of my invention. Fig. 2 is a sectional view through a portion of a building equipped|with my device. Fig. 3 is an elevation, on a somewhat-enlarged scale, of the casing for supporting the operating device. tral vertical section through the subject-matter of Fig. 3. Fig. 5 is ahorizontal sectional view on the line 5 5 of Fig. 3. Fig. t3 is adetail view illustrating the mannerin which the window-springs are applied.

Referring to the numerals of reference indicating corresponding parts in the several views, 1 indicates a building, and 2 its windows, having upper and lower sashes 3 and 4. The lower sashes are urged to their closed positions by springs 5,preferably located within spring-sockets 6 in the window-casing and connected at their opposite ends to the casing and to the bottom edge of the lower sash 4 behind the beads 7, which latter serve to partially house and obscure the springs when the sash is elevated in opposition thereto.

It has been premised that the primary object of the invention is to provide means for simultaneously operating the window-sashes to eifect the simultaneous opening or closing of the several Windows in a room, in any series of rooms, or throughout the entire house. I therefore provide a universal operating de- Fig. 4is a cenvice common to the sashes of the several windows and designed to be adj usted in various positions to effect the corresponding adjustment of thc several connected sashes. This operating device comprises a hollow casing 8 of the general form of an inverted truncated cone, with an annular flange 9 surrounding its base for the reception of securing-bolts,which pass through the flange and into the ceiling or other supporting-surface.

12 12, the., indicate a series of radial openings through the walls of the casing, adjacent to the upper end thereof, and designed for the reception of a series of radially -disposed grooved pulleys 13, mounted on shafts 14 and over which are passed the operating-cords, extending from the actuator to the sashes.

'The operator proper is in the form of a plunger-rod 14, extending into the interior of the casing and provided at its lower end with a ring or handle 15 below the casing and with a swiveled eyelet 16 at its upper end, to which the inner ends of the several operating-cords 17 are connected.` The sev eral cords extending radially from the upper end of the plunger-rod and passing over the grooved pulleys 13 are passed thence around guide-pulleys 1S, pendent from the ceiling and arranged to preserve the radial direction of each cord as it passes from the casing, and said cords are finally passed around vertical pulleys 19 and are connected to the lower window-sashes 4.

To guide the plunger in its reciprocatory movement, the casing 8 is provided at its lower end with a spider or grating 8f, which has a central opening 8b, and is, furthermore, provided with a series of radial slots 8", for a purpose as will be hereinafter more fully described. The plunger 14 extends loosely through the central opening in the spider or grating and being connected at its upper end to the cord 17 said plunger is effectually guided in its vertical movement. It will now appear that as the plunger is drawn down the operatingcords will effect the simultaneous elevation of the several Window-sashes, and

it is therefore evident that some means must be provided for facilitating the actuation of the plunger and for holding it in its various adjusted positions in order that the Windowsashes may be retained at the desired height IOO against the resistance opposed by the window-springs 6. Any form of such mechanism may be employed, but I prefer to provide a lateral stop-pin 20, projecting dia? Vin the spider or grating S at the lower end of the casing. Thus the adjustment of the windowsashes is effected by drawing down the handle 15 until the pin 2O clears the lower edge of the casing. The plunger is then rotated to bring the stop-pin opposite the locking-recesses of the desired depth to effect the proper adj ustment of the windows. The handle is then released and the springs 6 depress theisashes until the elevation of the plunger presents the stop-pin against the bottom Wall ofthe cooperating recess, when, as will he evident, farther movement of the plunger will be prevented and the windows will be retained at the desired elevation. A

'Ihe opposite limits of movement of the windows-thatis,the wide-open and the closed positions thereof-are accommodated by the shallowest and deepest recesses 2l, respectively, the recesses of intermediate depths being for the accommodation of the intermediate adjustments of the sashes.

As heretofore described,the window-sashes are yieldingly connected to the respective frames thereof by means of the coiled springs `5, which normally maintain the sashes in closed position, and when the operating de vice is released the said spring automatically closes the sashes.

Obviously my universal operating mechanism might be employed in various connections other than that illustrated and described. For instance, railroad-cars might be equipped with my device to permit the conductor or other authorized person to properly regulate the ventilation of the car by the uniform adjustment of the several windoW-sashes, or duplicate devices of any character capable of actuation through the medium of an operating-corde-as, for instance, mail-hooks on postal cars-might be equipped and actuated with the mechanism described. I therefore desire to reserve the right to effect such stru ctural changes, variations, and modifications as may be necessary to accommodate the varions applications of myinvention which may come properly within the scope of the protection prayed.

What I claim is- 1. The combination with a plurality of Windows, and the sashes thereof, of operating and having means to secure it in Various longitudinal positions, and an independent rotary movement for accomplishing its engagement with said means.

2. The combination with a plurality of windows and their sashes, of a casing, a reciprocatory operating device therein, a circumferential series of pulleys within the casing, and operati n g-cords passing over said pulleys and connected tothe operating device and to the sashes of the several windows.

3. In a device of the class described a casing, a reciprocatory and rotary operating device, a series of pulleys, operating-cords connected to the operating device and passed over the pulleys, and means for effecting the adjustment of the operating device by its rotation.

4. In a device of the class described, the combination with a substantially hollow casing having a series of longitudinal recesses o r slots of varying depth, of pulleys carried by the casing, operating-cords passing over the pulleys and into the interior of the casing, a reciprocatory and rotary rod located within the casing, having one end connected to the inner ends of the cords, and its opposite end provided with an operating-handle, and a laterally projecting stop pin for engagement 4with any of the longitudinal slots of the casing.'

5. In a deviceof the class described, the combination of a substantially hollow casing having a series of openings near one end, and provided at its opposite end with a series of longitudinal slots of varying lengths, and opening outward through the said opposite end of the casing, a spider or grating provided at the slotted end of the casing, and having a central opening, and radial slots communieating with the respective slots in the casing, pulleys mounted within the series of openings, operating-cords passing over the pulleys and into the interior of the casing, a reciprocatory and rotary plunger located within the casing and projecting through the central opening in the spider or grate, an operatinghandle provided at the outer end of the plunger, a swiveled connection between the inner end of the plunger and the operating-cords, and a stop-pin projecting laterally from the inner end of the plunger, and designed for engagement with any of the longitudinal slots of the casing.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence of two witnesses.
